No prior computer science training is necessary — I'll get you up to speed quickly, skipping all the overly academic stuff.

It's like math except it's an awesome, not-boring kind of math where you get to wave your hands through the details and just focus on what's basically happening. With big O notation, we express the runtime in terms of—brace yourself—how quickly it grows relative to the input, as the input gets arbitrarily large.Starting Price: $149 per 3 weeks -

Edabit
Edabit
When learning to code, most people get stuck on the "bridge" between memorizing syntax and understanding the logic that makes it all work. We believe the most effective way to learn a programming language is to break the process into three phases: 1. Memorize syntax 2. Solve problems 3. Make stuff Most beginners jump from memorizing syntax directly into making stuff (or trying) without fully understanding how syntax is used to solve problems. In other words, they haven't learned how to think like a programmer, yet they're trying to solve problems like a programmer. Edabit was created to bridge this gap, while also making the process fun and addictive.Starting Price: $10/month/user -

Codeforces constantly develops and we plan to improve the platform to give the participants the opportunity to organize their own contests, filling the project with learning content, developing Codeforces as a training and learning platform. Contests are regularly held on Codeforces. Participating in them is free and open to everybody. Every month we organize approximately six contests. To participate, you have to be registered on the site (if you have an OpenID or a Gmail account, then you won't even have to memorize the password) and register for the oncoming contest.
